Pull Request for Issue #37122.

Summary of Changes

Modified the Joomla\CMS\Cache\Cache::setWorkarounds to do a special treatment of the WebAssetManager assets before they are cached when caching a module.

Testing Instructions

• Install a new Joomla 4.1 site (I used the latest 4.1-dev as of February 23rd, 2022)
• Do NOT install any sample data
• Components, Contacts, Contacts, Add Your First Contact and create a contact in the Uncategorised group
• Menus, Main Menu, New
  • Menu item type: Contacts, List All Categories in a Contact category Tree
  • Title: Contacts
  • Alias: contacts
• Save & Close
• System, Global Configuration and set the following in the System tab
  • System Cache: ON - Conservative Caching (VERY IMPORTANT! Do not use Progressive, that caching type makes it harder to reproduce the issue as I explain in the very long technical explanation below)
  • Cache Handler: File
  • Platform Specific Caching: No
  • Cache Time (minutes): 60
• Click on Save & Close
• System, Clear Cache, Delete All

Go to the frontend of your site and click through IN THIS EXACT ORDER:

• Contacts
• Uncategorised
